ELECTRIC REGISTER FOR FLUID- -RESERVOIRS.

SPECIFICATION forming part of Letters Patent No. 300,490,1iated J'une1'7, 188%.

Application filed February 4, 1884.

(No model.)

of Newburg, in the county of Orange and State of New York, have inventeda new and Improved Electric Register for Fluid-Reservoirs, of which thefollowing is a full, clear, and exact description.

The object of my invention is to provide electro-mechanical means forregistering the height of water or other fluid in a reservoir at a pointdistant from the reservoir.

My invention consists in apparatus actuated by the rise and fall of thefluid in the reservoir, and adapted to make and break an electriccircuit, which circuit is connected with electromechanical registeringmechanism at a distant point, as will be hereinafter described andclaimed.

My invention is more particularly applicable to water-reservoirs, andwill therefore be described in this connection.

Referring to the accompanying drawing, the reservoir A is connected witha standpipe, 13, by a pipe, 0, so that water in the stand-pipe andreservoir will stand at the same level. N ear the stand-pipe B, andparallel with it, is placed a vertical pipe, D, and between the twopipes 13 1) there is a vertical standard, E, at the top of which isjournaled a wheel, F, whose diameter is equal to the distance between.the centers of the pipes 13 D. in the stand-pipe B is placed a float, a,and in the pipe 1) a weight, I), which is lighter than the float a, andthe float a'and weight b are connected by a cord, 0, running over thewheel F. The cord passes around the wheel, and is fastened to it at somepoint to insure the positive rotation of the wheel. Contactpoints (1project/from the periphery of the wheel F at equal intervals in positionto engage a, contact-spring, 0, held by a fixed support and connectedwith the wiref. A wire, 9, is in electrical communication with the wheel1 through the standard E, and the wires f r extend to a distant point,where the wire 9 communicates with the battery G, and the wire f isconnected through the binding-post h with one ofthe-terminals of anelectromagnet, H, whose outer terminal is connected with the battery G,completing the electric circuit. A lever, I, pivoted in the standard 1,extends over the poles of the eleetrmmagnet H, and carries an armature,z, to be acted on by the magnet, and has attached to its longer arm aspring-pawl, j, which engages the teeth of a ratchet-wheel, J. Above andbelow the longer arm of the lever I there are adjusting screws 70 Z, forlimiting the motion of the said lever, and to the shorter arm of thelever I is attached a spiral spring, m, for returning the said lever toits normal position after each operation of the electro magnet H. Theratchet-wheel J is mounted 011 a shaft, n, journaled in standards 0, andcarrying the index 1), which moves in front of a dial whose figures areshown in dotted lines, and indicates the movement of the ratchet-wheel.T, which, together with other parts of the apparatus, is inclosed inthe casing q. A pawl, r, pivoted on a fixed support, prevents retrogrademotion in the ratchet-wheel J. Above the wheel J is placed a bell, K, ofordinary construction, having an arm, 5, extending into the path of thepin t, so that the pin may engage the arm 8 and ring the bell. The pinmay be shifted to any of the holes in the spokes of the wheel adapted toreceive it, so that the time of ringing the bell K may be varied.

When the float a is elevated by the rise of the water in the stand-pipeB,the weight b, acting through the cord 0, turns the wheel F and bringsone after the other of the contact points (1 into contact with thespring e and completes the electric circuit through the mag net H, .andthe continued forward movement of the wheel carries each point away fromthe spring, breaking the electric circuit. \Vhen the water recedes inthe stand-pipe B, the float (0 falls and the wheel F is revolved in theopposite direction, but alternately making and breaking the circuit, asbefore. Each make and break of the circuit draws down the armature ofthe electro-magnet and moves the ratchet-wheel J forward, one toothindicating, by means of the index 1), that the water has risen or fallenthrough a distance represented by one tooth of the wheel F, and inwhichever direction the wheel F revolves the effect on the wheel J isthe same, always moving it forward one tooth for each contact be tweenthe points (1 and spring 0. The follow ing will serve as an example: Vewill-suppose the reservoir to be full-say twelve feetas shown 1n thedrawing, and the pump stopped. Xow, the decreasing :ligures ll. to t)indicate the quantit of water running out, and if the water has fallenfive feet the wheel will have turned to the figure 7 on the lefthandside. Thereupon the engineer starts his pump to fill the reservoiragain, and turns the wheel around to the '7 on the right of the wheel,or, in other words, to the 7 ol' the increasing numerals, when he willknow that every notch registered by the wheel will in dicate the depthcaused by the llowing in of the water, and alter the pump has ceased tooperate he will of course know that the rota tion of the wheel indicatesthe fall of the water. A pump will be used, of course, which can forcethe water into the reservoir faster than it can run out. 3y increasingor decreasing the circumference oi the wheel and the number of notchesand numerals, it may be made to serve with reservoirs of variouscapacities. lljumping into the reservoir A continues until it is iilled,and the pin 1 and bellarm s are arranged in relation to each other sothat the bell will ring when the reservoir is tall. The index p willthen point to figures indicating the greatest depth of water the reservoir is capable of holding. The figures on the dial from this point onare arranged in inverse order down to the zero, to represent thedecrease in the depth of water as the reservoir is emptied.

i l l l i My improved registering ilpllltl'ililllb is an plieable towater-reservoirs, oil-tanks, gasometers, and other forms of reservoirfor holding fluids. \Vhen applied, to gasometers, the standpipe 13 willbe dispensed with, and the cord 0 will be attached directly to thecontainingvessel oi" the gasometer, which is the equivalent 01" the Heata.

Qllaving thus described my invention, what I claim as new, and desire tosecure by '[iet ters latent, is-- 1. In an electric register forlluidaeservoirs, the combination, with the float a, opposing weight b,and cord 0, of the circuit-operating wheel I! and eontaetspring (r, thesaid wheel and spring being interposed in an electric cireuitcommunicating with a distant point, as specified.

2. The combination of the eireuit-operating wheel ll, Heat a, WCllQllhb, cord 0, contactspring circuit-wiresfy, and e]ectromechan iealreglstering mechanism, as described.

3. The combination of the eleetroamrgnet II, armaturelever l, pawl i,ratchet-wheel .T, and eircuit-emitrolling mechanism operated by the Heata, as described.
